Welcome to Stephen’s Website

I’ve written books on particular aspects of Astrobiology (Where is Everybody?), Cosmology (Measuring the Universe), Observatories (New Eyes on the Universe), Physics (Out of This World) and SF (All the Wonder that Would Be) — fields that are all fast-moving. Click on the relevant tab for updates.

My most recent book: published June 2017. It contains discussions of the history behind 10 science-fictional themes, and what modern science tells us might be possible. The book also contains my first published SF story — an homage to the Master, Isaac Asimov!

We are entering a golden age of cosmology — in large part thanks to new observatories that have astonishing capabilities. In this book I look at recent and planned observatories for all parts of the EM spectrum, as well as neutrino observatories, cosmic ray observatories and gravitational wave observatories.

My first book was a textbook about distance determination. It’s now slightly out of date (it came out just as the accelerating expansion of the universe became accepted) but it’s still a useful primer for undergraduate students.

Unfortunately, it’s expensive. (Blame the publishers, not me!) It’s still available (in hard-copy only) from the following sites:
